Hood River County Commissioners and Planning Commissioners held a joint meeting to discuss two major issues they will be discussing in coming weeks:  short-term rental regulations and a time, place, and manner ordinance for marijuana businesses.  County Administrator David Meriwether says there is a common thread in both of those issues:  determining in what zones the uses would be allowed.  In both cases, the planning commission will start the process of developing ordinances.  Public processes will begin at that panel, with recommendations to go to the County Commission.
